OBJECTIVES
After you have studied this chapter, you should be able to
Use the basic vocabulary of matter and energy
Distinguish between chemical and physical properties and between chemical andphysical changes
Recognize various forms of matter: homogeneous and heterogeneous mixtures,substances, compounds, and elements
Apply the concept of significant figures
Apply appropriate units to describe the results of measurement
Use the unit factor method to carry out conversions among units
Describe temperature measurements on various common scales, and convert betweenthese scales
Carry out calculations relating temperature change to heat absorbed or liberated
housands of practical questions are studied by chemists. A few of them are
How can we modify a useful drug so as to improve its effectiveness while mini-mizing any harmful or unpleasant side effects?
How can we develop better materials to be used as synthetic bone for replacementsurgery?
Which substances could help to avoid rejection of foreign tissue in organ transplants?
What improvements in fertilizers or pesticides can increase agricultural yields? Howcan this be done with minimal environmental danger?
How can we get the maximum work from a fuel while producing the least harmful emis-sions possible?
